What is the official name of the FGFRL1 gene?

The official name of this gene is “fibroblast growth factor receptor-like 1.”

FGFRL1 is the gene's official symbol. The FGFRL1 gene is also known by other names, listed below.

What is the normal function of the FGFRL1 gene?

The FGFRL1 gene produces a protein that is part of a family of fibroblast growth factor receptors that share similar structures and functions. This family of receptors plays a role in important processes such as cell division, cell growth and maturation, formation of blood vessels, wound healing, and embryo development. Proteins in the FGFR family span the cell membrane, so that one end of the protein remains inside the cell (the intracellular portion) and the other end sits on the outer surface of the cell. This positioning of the protein allows it to receive signals from outside the cell that help the cell respond to its environment.

The FGFRL1 protein is considerably shorter than other members of the FGFR family as it lacks a segment of the intracellular portion. Although the role of this receptor protein remains unknown, its structure indicates that it could interact with other FGFR proteins and potentially inhibit cell signaling. FGFRL1 gene activity has been detected in fetal cartilage. This finding indicates that the FGFRL1 gene may be involved in skeletal formation during development.

Does the FGFRL1 gene share characteristics with other genes?

The FGFRL1 gene belongs to a family of genes called immunoglobulin superfamily, I-set domain containing (immunoglobulin superfamily, I-set domain containing).

A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

Where is the FGFRL1 gene located?

Cytogenetic Location: 4p16

Molecular Location on chromosome 4: base pairs 1,011,821 to 1,026,897

The FGFRL1 gene is located on the short (p) arm of chromosome 4 at position 16.

The FGFRL1 gene is located on the short (p) arm of chromosome 4 at position 16.

More precisely, the FGFRL1 gene is located from base pair 1,011,821 to base pair 1,026,897 on chromosome 4.
